Belt-drive panel supply fans allow users to adjust the fans' blade speed and airflow. Belt-drive fans are better suited than direct-drive fans for high air flow (≥ 2000 cfm) or high static pressure (≥ 0.50") applications. Belts connect the fans' motors to their fan blades. These fans come with a drive package that includes a motor, pulleys, belts, and bushings, which saves time compared to purchasing all of these components separately.

Belt-drive fans are better suited than direct-drive fans for high airflow (≥ 2000 cfm) or high static pressure (≥ 0.50") applications. These fans do not come with a drive package, so users can select the compatible motor, pulleys, belts, and bushings that meet the specific demands of their application or use ones that they have on hand.
